rails loop
Certainly! Here's a breakdown of a loop in Ruby on Rails:
<% @users.each do |user| %>
<p><%= user.name %></p>
<% end %>
<% @users.each do |user| %>
: This line starts a loop that iterates over each element in the@users
array. Thedo
keyword marks the beginning of the loop, and|user|
defines a block variable to represent each element in the array during each iteration.<p><%= user.name %></p>
: Within the loop, this line accesses thename
attribute of the currentuser
object and outputs it within a paragraph tag using the<%= %>
erb tag.<% end %>
: This line marks the end of the loop block.
In summary, this code iterates over each user in the @users
array and outputs their names within paragraph tags.
